DESCRIPTION OF THE PREFERRED EMBODIMENTS

The objects, characteristics and effects of the present invention will become apparent with the detailed description of the preferred embodiments and the illustration of related drawings as follows.

With reference to FIGS. 1 to 3 for a heat dissipating protective cover of the present invention, the heat dissipating protective cover 10 comprises a bottom plate 1, a protective edge 2 disposed around the periphery of the bottom plate 1, a containing space 3 defined by an enclosure jointly formed by the bottom plate 1 and the protective edge 2 and provided for containing an electronic device, wherein the bottom plate 1 has a heat dissipating plate 4 installed therein, so that the heat generated by the operation of the electronic device installed with the protective cover can be dissipated through the heat dissipating plate 4 to the outside, and the good heat dissipation effect can dissipate the heat generated by the operation of the electronic device without the need of removing the protective cover 10 to assure the service life of the electronic device. In the meantime, the electronic device can be operated without the need of removing the protective cover 10 o that the protective cover will not be lost easily, and this design can eliminate the trouble and inconvenience of the users.

Preferably, the protective edge 2 is an elastic structure, such that the electronic device can be installed into the protective cover 10 easily to provide a convenient installation. More specifically, the protective edge 2 is a plastic protective edge with good elasticity. Of course, the entire backside of the bottom plate 1 can be coated with a plastic layer (not shown in the figure). Preferably, the bottom plate 1 has a cooling groove 11 formed thereon and at a position corresponding to the heat dissipating plate 4, and the heat dissipating plate 4 is coupled to the cooling groove 11. In this preferred embodiment, the heat dissipating plate 4 is adhered and secured into the cooling groove 11. Further, the bottom plate 1 is a metal bottom plate, and the good thermal conductivity of the metal of the heat dissipating plate 4 provides a good heat dissipation effect at the bottom plate 1, and such metal can be aluminum, silver, copper, or any other good conductive materials such as thermally conductive colloid.

In this preferred embodiment, the heat dissipating plate 4 has an area equal to 80%-90% of the bottom plate 1, so that the heat dissipating area of the protective cover 10 is large to achieve the good heat dissipation effect. In addition, a thin film (not shown in the figure) is preferred coated onto the heat dissipating plate 4, wherein the thin film can be a metal thin film such as a silver thin film. Of course, the invention is not limited to this material only, but other thin films with good thermal conductivity can be used as well.

Preferably, the protective edge 2 of the bottom plate 1 has an opening 21 formed thereon and provided for facilitating user to connect the electronic device with external connection lines or used for other purposes such as a speaker jack.
